Abstract (en)

[origin: EP3524703A1] The present invention provides a high thermal conductivity iron-copper (Fe-Cu) alloy and a method of manufacturing the same. The present invention provides an iron-copper alloy containing 55 to 95 atomic% of iron and 5 to 45 atomic% of copper. The present invention also provides an iron-copper alloy manufacturing method including a first step of preparing a melting furnace; a second step of adding iron and copper to the melting furnace and performing dissolution and molten metal formation so as to contain 55 to 95 atomic% of iron and 5 to 45 atomic% of copper based on the weight of the iron-copper alloy; a third step of stabilizing the molten metal; and a fourth step of pouring the stabilized molten metal into a casting mold and performing casting. The present invention provides an iron-copper alloy that is an iron-based alloy containing iron as a main component and having high thermal conductivity and mechanical properties along with, for example, an electromagnetic-wave shielding property and a soft magnetic property, which can be widely used for metal parts and electronic parts and machine parts.
